My understanding of Swing was that when in a modal dialog, which blocked
the EDT, a second EDT was fired up for the duration of the dialog to keep
the events flowing.
When you say, below, that only 1 GUI thread is supported (and that thread
is the native GUI thread), how are (will?) modal dialogs handled?
P.S. I've been trying to read Jonathan's article on dialogs on
fxexperience.com, but haven't been able to because I get redirected to

This would imply that there was more than on distinguished GUI thread
per process. JavaFX runs in the native GUI thread by design and more
than one GUI thread is not supported in JavaFX and on some platforms
